SPRING-MOTOR.

SPECIPTCATION forming part of Letters Patent No. 340,799, dated April27, 1886.

Application filed October 9. 1885. Serial No. 179,436. (No model.)

This invention relates to that class of springmotors which are employedfor operating sewing-machines, jewelers lathes, and similarlight'running machines, and in which the.

'powcr is transmitted from a coiled spring through a train of gearing tothe driving-shaft of the machine.

The object of my invention is to provide a 1 simple, compact, andnoiseless motor of this character; and the invention consists of theimprovements which will be hereinafter described, and pointed out in theclaims.

In the accompanying drawings, consisting of two sheets, Figure 1 is asectional elevation of my improved motor. Fig. 2 is a horizontal sectionin line m a, Fig. 1. Fig. 3 is a longitudinal sectional elevation inline y y, Fig- 1. Fig. 4 is a detached side elevation of thespringbarrel and alarm device. Fig. 5 is a fragmentary sectionalelevation of the brake. Fig. 6 is a cross-section in line w 00, Fig. 5.Fig. 7 is a cross-section in line 2 .2, Fig.

Like letters of reference refer to like parts in the several figures.

A represents the table, and A a portion of the frame of a sewing-machinesupported thereon.

a represents the driv i ng-shaft of the machine,

5 supported in hearings in the frame A, and provided with the usualdriving pulley, a, and fly-wheel a. t

B B 13* represent the hangers or frames of the motor, which are securedto the under side .0 of the table A and connected at their lower ends bybrace-rods b.

0 represents a horizontal shaft journaled in bearings in the frames BB", and O represents a drum or barrel, which is mounted 5 loosely on theshaft C and incloses a coiled spring, D. The barrel 0 is preferably castin two parts, 0 c, which are secured together by screws or bolts 0",inserted through lugs 0, formed on the adjacent sides of the parts 0 c.

The outer end of the spring D is secured to the barrel 0 by a nut, d,and its opposite end E and gear-wheel E are turned to wind the springDupon the shaft G. The wheel E is held from turning backwardly by theworm E.

F represents a toothed wheel mounted on an arbor, f, secured to one sideof the barrel C, and f is a tooth or projection formed on -or secured tothe shaft 0, and engaging .be-

tween the teeth on the wheel F in such manner that the wheel F is movedthe distance of one tooth at every revolution of the shaft 0. 7::

G represents an alarm bell secured to the side of the barrel 0, and g isa spring-haui- Iner, which is adapted to come in contact with a pin orstop, g, on the wheel F as the latter revolves. The stop 5/ is soarranged on the wheel F as to cause the hammerg to strike the bell andsound an alarm when the spring D has been sufficiently wound.

H represents a gear-wheel, which is secured to the opposite side of thespringbarrel C by screws 11, so as to revolve with the barrel.

2 i '1' represent short shafts or spindles j ournaled in hearings in theframes B B".

I I 1* represent gear-wheels, and J J J are spur pinions secured,respectively, to the 8 shafts ii The gear wheel H, secured to thespring-barrel O, meshes with the pinion J on the shaft i, and thegear-wheel I on the shaft 2' with the pinion J on the shaft i, and thegear-wheel 1 on the shaft t" with the pin- 3 ion J on the shaft 1'5",whereby lnotionis transmitted from the springbarrel O to the shaft zthrough the gearwheel H and pinion J, and from the shaft to the shaft ithrough the gear-wheel I and pinion J, and from the shaft t" to theshaft 6' by means of the gear-wheel I and pinion J K is a countershaftjournalcd in bearings formed in the hanging f ramcs I B 13* and providedwith apinion, it, which meshes with the gear-wheel I on the shaft iwhereby motion is transmitted from the shaft i to the shaft K.

' motion of the machine is arrested.

The shaft K is provided with a belt-pulley, L, which is connected withthe driving-pulley a of the sewing-machine by abelt, Z. Motion is inthis manner transmitted from the spring D through the train of gearingto the drivingshaft of the sewing-machine.

M represents a brake-pulley secured to the shaft K so as to turntherewith.

' N represents the brake rod, which is provided at its lower end with ahorizontal pressure-finger, n, which is adapted to bear against thebrake-pulley M and stop the motion of the machine. The brake-rod N isguided near its lower end by a pin or screw, 0, secured to the frame Band passing through a slot, 0, formed in the brakerod. The upper end ofthe rod N extends through an openingin the table A, and is pivoted tothe short arm 1) of a handlever, P, which latter is pivoted to avertical post, q, secured to the top of the table A.

r is a fiat or othersuitable spring secured to the frame B and bearingagainst the brakerod N, whereby the pressure-fingern is forced againstthe brake-wheel. Upon pressing down upon the long arm 1) of thehand-lever P the rod N is raised until the horizontal portion a of thefinger n is forced against the inner face of the rim of the brake wheel,whereby the \Vhen the brake is thus applied, the spring-barrel O is heldfrom turning through the gear-wheel H and train of gearing communicatingwith the shaft of the brake-wheel.

When it is desired to wind up the spring I), the brake is applied andthe shaft 0 revolved, by means of the hand-crank e and wornrgear E E,until the stop 9 comes in contact with the hammer and causes the latterto strike the bell and sound the alarm, when the oper ator is informedthat the spring has been wound sufficiently tight. The arm 3) of thehand-lever is now raised, so as to release the brake, when the pressureof the spring D upon the barrel (1" will cause the latter to revolve andset the train of gearing in motion. gear E E.

If desired, the spring may be wound upon the shaft 0 while the machineis in motion by turning the handcrank 6 The wornrwheel may be made rightor left handed,to suit the different styles of machines to which themotor is applied.

\Vhen it is desired to regulate the speed of the machine, the brake-rodN is raised sufficiently to permit the spring 1- to press the side Theshaft 0 is held at rest by the wormof the finger against the face of thebrake Wheel without touching the rim of the wheel.

My improved motor is simple in construction and is entirely noiseless,and can be readily applied to any sewing machine or other light runningmachines where light power is required.

I claim as my invention-- 1.- In a spring-motor, the combination,withthe shaft 0, and the drum G,mounted loosely on said shaft, of a spring.I), connected at one end to the drum Gand atits opposite end to theshaft 0, a gear-wheel, E, secured to the shaft 0, and a worm-wheel, E,engaging with the gear-wheel E, substantially as set forth.
